Elastic Collision problem

  1. Feb 7, 2007 #1
    1. The problem statement, all variables and given/known data

    A moving shuffleboard puck has a glancing collision with a stationary puck of the same mass. If friction is negligible, what are the speeds of the pucks after the collision?

    3. The attempt at a solution
    I ended up with this:
    0.95 = Vx1*cos50 + Vx2*cos40
    0= Vy1*sin50 - Vy2*sin40

    I know that both momentum and energy are conserved in elastic collision but I got no idea how to actually apply the concept. I think i'm looking too much into it and missing something simple. Thanks

    You can apply it in a similar way to the way you used conservation of momentum. What is the equation for conservation of kinetic energy? Split this up into x and y components ike you did with the momentum.
